RE: [httpclient] How to send and recieve Serialized Object usingHttpClient

[Sanjeev Tripathi <sa...@parago.com>]

Actually request parameter that I set in HttpCleint I can use in servlet
But
There is no way (or at least I don't know) to retrieve request
attribute/parameter in http client those set in servlet. This is very
simple in jsp but in http client I need to write object to
outputstream{ObjectOutputStream oos = new
ObjectOutputStream(response.getOutputStream())}

To work this I need to set content type as follows

response.setContentType("application/octet-stream");

I don't want to set content type "application/octet-stream" that's our
goal.

Every thing is fine in client side.

Thanks.

If you post the code you're using, someone can probably help.  I'm quite
lost by now trying to remember who suggested what.

If you're getting all the way to the base64 encoded byte[], can't you
turn
it into a String and then use that as the value of a request parameter
for
the POST?  Wasn't that the original goal, to serialize an object,
base-64
encode the binary data, and send it to the server as text?

If so, there's a String constructor that takes a byte[], (and you can
specify the charset if necessary).

Can you list the steps you're taking, and post the code that is not working?

I _think_ you're stuck on sending a base 64 encoded serialized object back
to the client, but I'm not certain.  If that's the case, please show the
server-side code you're using to send the response, and then what you've
done on the client.
